Freeze Frame Data [09/2014 - 10/2015]

  1. FREEZE FRAME DATA 
    NOTE:
    • It is difficult to show the specified values (judgment values) clearly because freeze frame data values change significantly due to differences in measurement conditions, surroundings, or vehicle conditions. For this reason, there may be a problem even when the values are within specifications.
    • Turn the power switch on (IG) and park the vehicle on a level surface. Check the freeze frame data by using the Techstream.
    1. Connect the Techstream to the DLC3.
    2. Turn the power switch on (IG) and check the freeze frame data by following the prompts on the Techstream display screen.
